XXV1l1 PROCEEDINGS. 
Tairp Orpinary MEETING. 
City Council Chamber, City Hall, Halifax, 13th January, 1896. 
The PresipDENT in the chair. 
A paper by Pror. A. E. Cotpwe.t, entitled : “‘ Notes on the Super- 
ficial Geology of Kings County, N. 5.,” was read by the Corresponding 
Secretary. (See Transactions, p. 171). 
The paper was discussed by Drs. Murpuy and Girpry, and Mgssrs, 
Buiack, Hemeoy, McKay and BisHop. 
Pror. J. G. MacGrecor read a ‘‘ Note on Newton’s Third Law of 
Motion.”—In former papers (Trans. Roy. Soc. Can., vol. x, see 11, p. 3, 
(1892) and Phil. Mag. ser. 5, vol. xxxvi, (1893), p. 244) he had 
endeavoured to show that the attempt supposed by some writers to 
have been made by Newton and actually made by Maxwell and Lodge, 
to deduce the third of Newton’s Laws of Motion from the first, was 
unsuccessful, the reasoning by which the deduction was made being 
fallacious. In the present paper attention was directed to the attempt 
made by Mr. R. T. Glazebrook, F. R. S., in his Elementary Text Book 
of Dynamics (Cambridge University Press, 1895, p. 151) to re-state 
the deduction in a new form, the object of the paper being to show that 
Glazebrook’s deduction involved the same fallacy as those of Maxwell 
and Lodge. 
FourtH Orpinary MEETING. 
City Council Chamber, Halifax, 10th February, 1896. 
The PRESIDENT in the chair. 
Dr. A. H. MacKay presented for examination by the members of 
the Institute, a flag of reddish freestone five times the linear dimensions 
of the reduced photographic representation given below, and bearing on 
one face a number of very distinct and beautiful dendritic markings 
representing very closely in general outline the figures and color of some 
of the finely sprayed, red seaweeds for which they were popularly 
taken. But, by the ordinary blowpipe tests, the simulated fronds of the 
red alga turned out to be an oxide of manganese instead of a fossil, and
